* This -invention relatesY tohclushion filling :machinesfand more V.especially to amachine 'of the pusher type capable of being operated' Aby one person. e In the past, machines for lling upholstered furniture have been very ponderous and required a great deal of space in' which `tooperate them. This entailed a great-'initial expenditure and fa large operating cost dueto the addedspace necessaryfor this machine, and the need'oiI atleast two people to'operate it. -I

It is an object of inventiontoimprove the old type of mechanismby providing` a -device which can be readily operated :by one person. I accomplish this byineansof asini-- `ple mechanical assembly actuated by the op" erator and acting on the pusher rod to propel thef'i'illing 'material through the 'filling `box and into the covering vfor the cushion.

` Itis another objectof'my invention to provide a plurality of dogs'or iinrgerslcontacting with teeth ontlie' pusher rod, yone of said dogs acted on by the actuatingineans topush the pusher rod through' the lilling box., andthe other dog preventing a backward movement of the pusher rod. Y

'It' is anothenobject of my' invention to provide a device acted'on by the operator, rod

i Itfg -Il'OrheIf Object of my invention'ito Aprovide a. device which be simply and cheaply constructed.

VMy invention possessesmany otherv ad-` vantages, and has other objects which bemadefmore easily apparent from a `consideration of one embodiment of my invention. For this' purpose I have shown a form in .the drawings accompanyingl and forming cpart lofthe present speciiication. I shall now' proceed to describe this ifforin in detail', which illustrates the general principles ofifny invention; but it is 'to beunderstood that thisV detailed description isV not tobe taken in a limiting sense, since the'scope of my invention is best detined by theappended claims.

VReferring to thev drawings:

Figure 1 is a sideV elevational View of my .cushion lillingmachine; Y

Fig. 2 is a? plan view thereof;.. Fig. 3 is .a front end view with parts in :i5 section; c. Y Figa' is a detailed sectionalvview 'ofa part ofmygmachine; and i Fig. 5 is a section along the plane 5--501 Figetb v 1 Y 1960 My machine comprises a base 10 having an upright support or standard 11V secured theretof At the vupper extremityV of the standard 11, Iv provide as-transversesupport 412 (Figs. land 4) extending parallelto and "65 overlying a portion of the base 10. Intermediate the endof the support12 and the filling box ltadapted to contain the vfilling material. The box 111 is mountedon the support 12l so that the` central portion therefor directly overlies the-.standard 11. r`Ihe boxr14 consistsof twosections 15, 16 v(Fig.

VV3) one telescoped within theother in order to provide a meansioi`- adjusting the width lthereof to comply with the width of the cushion cover tobe filled. `The means for adjusting the width of the box 11i comprises a st-a- 180 tionary screwv `17 mounted 'in internally threaded blocks '18. and 19; and supported in .the support 12;V f Integral withthe blocks 18 and `19 are -elevated extensions 2OV secured at 17 has yits ends threaded in opposite directions, so thatl by turning the` crank 22 attached'to the screw, in one direction the blocks 18, 19 carrying the sections 15, 16 will move inopposite directions on the screw 17 "'90 and thus make the width of the box 14 wider or smaller, dependingon the direction in whicli'the lcranl22 is turned. The screw 17 fat `the end adjacent the crank 22 has a re- "Ingorder'to'- push the iillingimaterial coniitained in the'box y14 into a cushion cover, I `provide anlI beam 25 with teeth 26 ystruck plate 27 secured to the beam 25 in any suitable manner, such as by angle irons 28. The

. beam 25 is supported in a position horizontal to support 12 in a guide 29 and a guide 30, thus assuring a horizontal movement to the beam k25 when pushed throughthe box 14 in a manner to be described. Theguide 30 is an upstanding member integrally sel cured to the end of the supporty 12, and the guide 29 is secured tothe support 12'ata point adjacent the rear'e'nd of the box 14.

The beam and the plate 27j .will now be .termed a pusher4 rod 31. Inforder to `push the filling material Voutfof the boxV 14, I provide a. collar 32 encircling the beam 25 (Fig. 5). In a slot 33'in thetop of. the collar 32, I pivotally secure anfactuating dog 34Ap`ivoted on a rod 35 connected to the vcollar32. It will, be noted that the dog 34 contacts at 36with theV teeth 26v of the beam 24. In order to maintain the'dog 34 in Contact with the teeth '26, I provide va spring`37 vmounted in a recess 38 in the collar 32 and exerting an upward force-onithe end'39 of the dog 34. l

The pusher rod 31 is actuated by the dog 34 through the intermediary ora simple level` arrangement.v This 'consists of'a Vfoot pedal 40 pivoted at 41 to the YstayV 13 and guided Y Y ina guide 42 securedtothe standard 11. To

the foot pedal 40 and the standard 11, Ivpiv- `otallysecure a lever mechanism consisting of members'43 and-'44. The'member 44 is piv- Dot'e'dly secured at one end to the standard 11, and at the'other end to the member 43.

"A link'element 45 is connected to an intermediate point Von the member 44 and toa depending ear 46 on the collar 34.` Itis` thus apparent that `a downward movement of the footpedal 40 will acty onthe elements 43, 44 and .to move the collar 34 and in turn the pusher rod 31, throughthe intermediary of Y the dog 34 towards the box 14. I provide a strong coiled spring 47 connected'toV an ear 48r on the support-.1.2 and tothe foot pedal V4Oatr49 in ordertoassure the return of the foot pedal 40 to its original positionupon releasev of the actuating force.. A downward movement 'of the footpedal 40'wil`l tend to lmove the pusher rod 31 only a short distance through the box 14,.and when the vfoot pedal `40'returns to its original position, the collar 32 and the dog 34 is 'forced backwards `over the teethj26,rby'means of the lever mechanism 43, 44 Vand Y45. It is thus apparent, that in order to push the pusher rod 31 through the box 14, the. 'foot pedal-40 has toY be depressed f, a sufficient number of times.

A" @the pusher rod 31 progressed through the box 14, 'the iilling'material therein is compressed and exerts aback pressure tending to force the pusher rod 31 backwards. Inorder to Vprevent this backward movement ofthe vpusher'rod 31I provide a dog 50 contacting with the'teeth 26 and pivoted at 51 in the `,guide 30. The dog 50is maintained inzthis 'position' by a coiled spring 52 which is secured to the dog 50 at one end, and to the guide 30, by means of a bolt 53, at the other end. To release the dogj50 from the teeth 26, I provide a connecting rod 54 screw- .threaded at 55 to the dog 50, and a link 55 connected to the lower extremity ofthe rod 54. The link 55 is readily accessible to the operator. and by pulling thereon, the dog 50 is 'forced upwards against the .action of the spring 52 to the position indicated in dotted lines. (Fig-4.) Y

` The 'parts 15,716 forming the box14 are nhinged 'at 56 to provide lids that can be read- 'A i ily opened in ordertofiill the box 44 with 'the The lids are maintained in -iilling material. aclosed position by means'` of an L-shaped -member 57 pivoted' 'in' a socketff58 in the ofY rotation'y inY a, hori- 31 due to the pressure existing in the box 14.

In its backward movement, it carries the dog 34with it, and the end 39 thereof contacts with the dog 50'and releases they dog 34' from the teeth against action of the spring '37.
